Problems solved by technology
OLED's light-emitting organic materials have a short life span of blue-green temperature, so only organic light-emitting materials with warm color temperatures such as red, yellow, or orange are used in lighting applications. On the one hand, the manufacturing cost is reduced, and on the other hand, the life of the product is also longer. Therefore, the OLED lighting device will tend to have a warm color temperature
[0003] The color temperature of white light in the prior art is not easy to control. When it is necessary to adjust the cool and warm colors of white light, various light sources will be used, which increases the manufacturing cost and is inconvenient to adjust

The invention discloses an OLED lighting device with adjustable white light color temperature. The OLED lighting device with adjustable white light color temperature comprises an OLED light source, a blue light source is arranged on the opposite side of the OLED light source, brackets symmetrically distributed are arranged between the two ends of the OLED light source and the blue light source, and the blue light source comprises a base plate and LED crystal grains. According to the OLED lighting device with adjustable white the light color temperature, OLEDs with warm color temperature such as red yellow or orange light are used as the light source to replace existing indoor lighting devices, and the blue light source is used for controlling the color temperature of the light emitted by the OLEDs, so that when in use, the two light sources can be mixed to form the white light with cold color temperature or warm color temperature, the white light with the cold color temperature or warm color temperature is adjusted according to the intensity of the blue light source, and the adjustment is convenient; and the OLED light source can be independently used for emitting a light source with warmer color temperature, so that requirements of people for color temperature are met, the manufacturing cost can be reduced, and the product life is prolonged. The blue light source is additionally arranged to adjust the color temperature on the basis of the OLED light source with the warm color temperature so that the OLED lighting device can be used in indoor lighting devices with all color temperature.
Description
technical field [0001] The invention relates to the field of OLED lighting, in particular to an OLED lighting device with adjustable white light color temperature. Background technique [0002] The application of OLED has been changing with each passing day. It is not only used in mobile phones and other displays, but also in lighting. For example, the taillights of some car models have already advertised the use of OLED. OLED's light-emitting organic materials have a short lifespan in blue-green temperature, so only organic light-emitting materials with warm color temperatures such as red, yellow, or orange are used in lighting applications. On the one hand, the manufacturing cost is reduced, and on the other hand, the life of the product is also longer. Therefore, the OLED lighting device tends to have a warm color temperature. [0003] The color temperature of white light in the prior art is not easy to control. When it is necessary to adjust the cool and warm colors of ...
